How to Permanently Disable Efficiency Mode for Google Chrome in Windows 10/11 {Easiest Method}
If you’ve used the Google Chrome browser before, you’ve probably come across one of its biggest problems: memory usage. Chrome has always been a browser that consumes a lot of active RAM. While Google has improved Chrome’s memory usage over the years, the problem has never gone away completely.
Fortunately, Windows has stepped ahead with a system feature that helps reduce the demand that apps like Chrome place on your system memory. This low-power mode can help you save power and improve overall system performance by reducing the CPU and RAM usage of your browser tabs.
However, this can slow down your browser, so it's best to disable it. To disable efficiency mode for Google Chrome on Windows, follow these steps.
